You cannot divide light from darkness any more than you can divide heat from cold. Cold is an absence of heat, and darkness is an absence of light. I suppose that we have no conception of absolute cold. We know only degrees of heat. Twenty degrees below zero is just twenty degrees warmer than forty degrees below zero. Neither cold nor darkness are entities, and these words express simply either the absolute or partial absence of heat or light. I cannot conceive how light can be divided from darkness, but I can conceive how a barbarian several thousand years ago, writing upon a subject about which he knew nothing, could make a mistake. The creator of light could not have written in this way. If such a being exists, he must have known the nature of that "mode of motion" that paints the earth on every eye, and clothes in garments seven-hued this universe of worlds. VII. TUESDAY. We are next informed by Moses that "God of the waters, and let it divide the waters from the waters;" and that "God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament." What did the writer mean by the word firmament? Theologians now tell us that he meant an "expanse." This will not do. How could an expanse divide the waters from the waters, so that the waters above the expanse would not fall into and mingle with the waters below the expanse? The truth is that Moses regarded the firmament as a solid affair. It was where God lived, and where water was kept. It was for this reason that they used to pray for rain. They supposed that some angel could with a lever raise a gate and let out the quantity of moisture desired. It was with the water from this firmament that the world was drowned when the windows of heaven were opened. It was in this said Let there be a firmament in the midst firmament that the sons of God lived--the sons who "saw the daughters of men that they were fair and took them wives of all which they chose." The issue of such marriages were giants, and "the same became mighty men which were of old, men of renown." Nothing is clearer than that Moses regarded the firmament as a vast material division that separated the waters of the world, and upon whose floor God lived, surrounded by his sons. In no other way could he account for rain. Where did the water come from? He knew nothing about the laws of evaporation. He did not know that the sun wooed with amorous kisses the waves of the sea, and that they, clad in glorified mist rising to meet their lover, were, by disappointment, changed to tears and fell as rain. The idea that the firmament was the abode of the Deity must have been in the mind of Moses when he related the dream of Jacob. "And he dreamed, and behold, a ladder set upon the earth and the top of it reached to heaven; and behold the angels of God ascending and descending on it; and behold the Lord stood above it and said, I am the Lord God."
